Since all the OEM diesels have had EGR coolers for many years now I would think so.
But one of the first things diesel owners do is delete the EGR, se we don't dwell on it much. We do this because EGR does not increse MPG unless in cold climates on vehicles that are not worked very hard, even then it more of a function of the EGR cooler warming coolant than the EGR its self.
